I have the same problem with “clicks and no response”, some clicks work immediately, some works if you click more than 2-5 and some don’t work at all.
The problem started the same day or the next with the lag/backbone problem and nothing change until now.
Is it problem with the specific browser or/and os (Chrome on Win10) ? Yes it is.
You can call it client lag or whatever but when I play Sparta with beta app it is works without the clicks problem (Not without Problems).

“I recommend that you try playing the game using another connection (e.g. cable instead of Wi-Fi) if possible. You can also consider playing the game using a different browser. The gaming experience may be different.”
My connection is 24Mbit ADSL and I try Sparta with Chrome, Firefox, Edge.
Each browser has his own issue and none works Good enough.
Plarium must solve all problems if want from Players to stay and play their games.
Players could be beta testers for a while but the main purpose from them is to Play not to Beta Test the game/s.
If you Want Beta Testers for your Game you must hire Real Ones.
If you don’t solve the Game Problems fast enough the Players leave the game sooner or later.
